Figure 4

Differentially expressed genes in the two subgroups of glioblastomas with strong and weak TGFβ response (in the Freije dataset). The data were Z-score transformed and the color range was indicated by the color bar below the heatmap. Each column represents a glioblastoma sample and the tumor identification number is shown at the bottom of the column. Each row represents one of the 1386 differentially expressed gene with p < 0.001 and fold change >1.7. The classical TGFβ downstream targets in Table 2 are highlighted as green.
